i have a wix forum with over 3k members and a facebook group page with over 18k members. I've been using the Facebook group alot more lately since Google+ is dying and I noticed how much more I am kept busy on there cause I am dinged for each notification which keeps me more instantly able to respond to all activity im in involved in, such as replies, tagged etc. My wix forum peer to peer chat has notifying dings when messaged and I think we should have the option for notification dings on our Wix forum as well like Facebook. It really does help the members keep engaged and more interactive with each other. I know many may not like this idea but as a site/forum owner i think we should be able to have that as part of our site by enabling it, with the options for individual forum members to mute it if its disturbing to them. I really think it helps keep them glued to the site Please consider. It could be fun especially when Wix adds member badges

Hi John, if you had the Wix Mobile application, you could get sound notifications. But if you use only mobile version and you get notified via your Gmail, then you should set your Gmail sound notifications louder. If I misunderstood you, please write me directly:)
We do, for private messaging.
